In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Mechanism of cis-trans photoisomerization of dichlorodipyridineplatinum,(II), published in 1971, which mentions a compound: 15227-42-6, mainly applied to dichlorodipyridineplatinum photoisomerization; complex dichlorodipyridineplatinum photoisomerization; platinum dichlorodipyridine photoisomerization, Product Details of 15227-42-6.
The photochem. behavior of cis- and trans-Pt(py)2Cl2 in CHCl3 solutions has been investigated using 313 nm light. The cis isomer undergoes 2 simultaneous photoreactions, one being an intramol. photoisomerization process (Φisom ∼0.04) and the other a photodissociation reaction involving the pyridine ligand (Φdiss ∼ 0.025). This latter photoreaction provides an intermol. path for the cis → trans isomerization since its products (namely, free pyridine and Pt-containing species) recombine thermally to give cis- and trans-Pt(py)2Cl2 in a 2:1 ratio. The trans isomer undergoes photoisomerization and pyridine release but with much lower quantum yields (∼0.001). Qual. results concerning the photochem. behavior of the above complexes in MeOH solutions upon 254 or 313 nm irradiation are also reported.
Although many compounds look similar to this compound(15227-42-6)Product Details of 15227-42-6, numerous studies have shown that this compound(SMILES:[Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2), has unique advantages.
